Increasing Production + Reducing Waste

A growing concern facing various food and beverage production facilities is the issue of treating high strength waste created during production. One example is breweries, which produce wastewater with high concentrations of COD, BOD and TSS resulting in elevated surcharge or haul away costs. Using the FMX enables food and beverage production facilities to treat the high strength waste, reducing costs related to surcharges or haul away. In some cases, raw materials in the waste can be recovered and sold as an animal feedstock, creating a win-win situation for these facilities.

Food & Beverage Wastewater

Fish Thawing Water Treatment

Client: Fish Canning Facility, U.S.A.
Goal: Bacteria, micron and submicron organic particle removal, client would like to keep the thaw water useable for at least one week instead of the current 36 hour operation
Membrane: UF, 90,000 Dalton (FU-S400HB)
Average Flux: 160 liter / (m2 • hr) [94.1 GFD]
Note: Full scale recirculation flow rate of 3,000GPM (680 m3/hr)

Thawing Water: Feed (left) and Filtrate (right)

Winery Distillation Bottoms

Client: Commercial Winery, U.S.A.
Goal: Remove phosphorus and nitrogen from irrigation water
Membrane: NF
Average Flux: 64 liter / (m2 • h) [38 GFD]
Note: Concentrated water to be used as feedstock for anaerobic digester

Feed (left), Concentrate (center), and Permeate (right)

Grain Wash Process Water Treatment

Client: Commercial Brewery, U.S.A.
Goal: Concentrate grain wash water at 3% TS to greater than 12% TS so it can be used as animal feedstock. Reduce tipping fees associated with volume of grain wash water
Membrane: UF, 90,000 Dalton (FU-S400HB)
Average Flux: 124 liter / (m2 • hr) [85.7 GFD]
Note: Pilot study operated at high temperature (48 o C/118o F)

Wastewater solids removal: Feed (left), concentrate (center), and filtrate (right)

Beer Recovery from Trub Yeast

Client: Commercial Brewery, South Korea
Goal: Recover beer from fermentation bottoms
Membrane: NF
Average Flux: 10 liter / (m2 • hr) [6 GFD]
Note: Uniform RDF (*amount of sugar consumed) indicates the vortices do not harm the yeast (forced lysis)

Beer recovery from yeast: Feed (left), filtrate (right)

Bakery Wastewater Treatment

Screen Shot 2017-10-26 at 5.02.50 PM.png

Client: Commercial Bakery, U.S.A.
Goal: Reduce and treat the water from wash cycle
Membrane: NF
Average Flux: 90 liter / (m2 • h) [53 GFD]
Note: FMX helps prevent bio-fouling more than conventional membrane systems

Beer recovery process from waste yeast

When the fermentation process is completed in beer manufacturing, the yeast sinks to the bottom of the fermentation tank. After the fermentation process, the sediment at the bottom of the fermentation tank is discarded while the product is moved to the storage tank. The yeast that has precipitated in the storage tank is also periodically thrown out.

The total amount of discarded sediment accounts for 1.5 - 2% of the total beer production volume. The sediment at the bottom of the fermentation tank contains not only yeast but also a high percentage of beer that is not recovered and is lost. The concentration of the sediment ranges from TS 5 - 25% .

Although the flux was not high (5-10 LMH), FMX was able to recover 30 - 50% of beer from the waste yeast.

In the end, the amount of beer recovered by FMX from waste yeast accounted for 1% of the total beer production volume. Implementation of FMX also decreased dewatering and hauling costs.

Removing Fine Particles in Coffee Manufacturing Process

FMX has effectively removed fine particles in coffee manufacturing process.

The extract produced from grinding & dripping stage had TS 12- 15% and could not be processed by conventional membrane process. When the extract was filtered through FMX, the final TS was 9 - 10% and the turbidity was 17.4 - 98 NTU.

By adjusting the membrane pore size, FMX can create various flavors and types of coffee.
